a To on 'whom it may concern:

' Waitsbur'g,

Be it known that I, MARTIN WELLER, a citizen of the United States, residing at in the county of Walla Walla and State-of Washington, have invented cer- .tain new and useful Improvements in Rotary Brushes, of which the following is a specification.

This invention relates to brushes which operate by a rotary movement,-and its obis to provide a brush of this kind havmg a wide range of usefulness.

The invention also has for its object to provide a novel and improved means for driving thebrush, and also to provide a means for feeding water to the brush and thus obtain a fountain? brush.

Other objects and advantages of the invention will be pointed out in the detailed description appearing hereinafter, reference being had to he accompanying drawings forming a part of this specification.

In the drawings- Figure 1 is a side elevation of partly in section" Fig. 2 is a sim' ar view ject the device,

showing a slightl difi'erent arrangement of-parts;

and Fig. its supporting 15. A gasket 16 is placed on 11 and the cover plate is clamped down on the asket by the screw ring. 4%

. mentioned at the open end, and the secondv Fig. 3 is a plan view of a motor;

Figs. 4:, 5 and 6 are plan views of certain parts of the device detached; Fig. 7

is a plan view of another motor, 8 is a cross section thereof, with shaft partly in section. Referring specifically to the drawings, 10 denotes a casing which is preferably made of sheet metal, and has ofisets to glve it" a neat appearance, and at the same time to provide internal annular shoulders 11, 12 and 13, respectively. The casing is aspen at one end, and its other end is close f by a cover plate letheld in place by a screw ring the shoulder he easing is divi ed into three compartments indicated at 17, 18 and 19, respectively, the first mentioned being at the closed end, and the last mentioned in the middle.

In the end compartment 17 is located a rotary motor, which is a water wheel of any but preferably one of the impulse turbine type.

approved design,

Thewheel is comand bottom plates 20 posed of spacedtop and vanes 22 therebeand 21, respectively,

1 tween. The wheel is fixed on a shaft 23 'the wheel and not thereto. The two last mehtione mountedin the center of the casing 10,

the wheel being threaded to- ,the shoulder 12. This ring extends inward as far as the periphery of the wheel and thus compels the water to travel I to'pass directly into the compartment 18.

The water inlet to the compartment 17 is through the side thereof, the same having a nipple 28 to which a sup ly pipe 29 is connected, the latter being of such length that it may be used as a handle. The compartment 18 has a water outlet 30 in its side which may be closed by a plug 31; or a discharge pipe or hose 31 may be attached thereto. Three outlets are preferably provided, one directly beneath the inlet 28, and the other two at ri ht angles openings are provided in order that the water may readily escape, and to reduce the back pressure to a minimum. Without these additional outlets, when the work is such that the handle 29. is held horizontally, the cas ing 10 would naturally remain half full of water, which would be an impediment to the action of the water wheel.

In the end compartment 19 is mounted a brush composed of a head 32 and bristle tufts 33. The brush is fixed on the shaft 23 by being screwed thereon as shown at 34 against a nut 35. A binding nut at the bot tom may be provided if necessary. The brush tufts project a sufiicient distance from. the open end of the casing to reach the surface to be operated on.

On the-shoulder '13 seats a disk 36 having openings 37. The disk also has a central opening through which the shaft 23 passes to provide a support or hearing for the latter. Theshaft has a collar 38 resting on a bushing 39 supported bythe center of the disk 36. The openings 37. are provided for the purpose of allowing the water to pass and discharge on the brush. Should it be desired to use the brush dry, a solid plate or through as shown in Fig. 2, to close the openings 37.

This disk 36 has a central opening to ac- .and it can be used for scru dusting and sweeping automobiles, carriages,-

commodate the bushing 39, and it may be made of metal, leather or any other suitable material. The bushing 39 also acts as abearing for the shaft 23. When the disk 36 is in place it serves as a gate to shutoff the flow of water from the water wheel to the brush. 1

The brush head 32' has perforations 40 alternating with the tufts 33 to provide an ample waterway. 7 It will be understood that the water passes through these perforations to the brush tufts 33.

The shaft 23 is hollow and its upper end which is located in the compartment 17 has side openings 41. The end of the shaft to which the brush is attached isfitted with: a plug 42. Should it be desired to have only a small amount ofwater flow to the brush, the cover plate 36 is inserted in place and the plug 42 is removed. The surplus water in the compartment 17 now enters-the shaft 23 through the inlet openings 41 and runs down the inside of the shaft and is discharged into the center of the brush. By

fitting a discharge pipe 31*? to the outlets 30 the excess water is conveniently carried away.

When the brush is to be used for dusting, sweepin or other dry work, compressed air will e used for rotating it, a fan 44 being substituted for'the water wheel. This fan is shown in Figs. 7 and 8.

A bearing 45 for the upper end of the shaft 23 is a hollow nut which is screwed into the cover plate 14 and by which any wear may be ta en up. Shims may be inserted in thenut if required.

While the-preferred embodiment of the invention has been shown, it will be understood that various'ehanges in the structural details may be made without a departure from the spirit and scope of the invention as claimed hereinafter. Different sizes and shapes of brushes and casings maybe used.

and the areas of the water passages may be varied to produce the best results.

The device has a wide range of'usefulness, hing, cleaning,

floors, windows, walls, ceilings, upholster- I ings, etc. It is therefore ageneral utility is provided with perforations, a water'wheel cleaner, and the rotary movement of the 7 brush makes its .work rapid and thorough.
